Ronald had exhibitions in New Zealand in the beginning of the year and in the fall in Amsterdam in 2024.
New exhibitions for 2025 and further are in preparation.
Ronald is also involved in Moongallery, an international collaboration to create and bring art to the moon. A group of artists, including Ronald, create each small pieces of art (a cubicle of 1 cm3), which will be attached to the lunar lander. After a successful landing, it will be the first work of art on the moon! It may take a few years yet before that happens. The Moongallery has been in space for 10 months and has safely returned to earth! It found itself in the ISS Space Station circling Earth! More information on the project: www.moongallery.eu
